+Usual issue with rpctrace: it does not support fork().
+
+I've checked a backtrace in gdb, got this:
+
+ 0x0105af6c in mach_msg_trap ()
+   at /build/eglibc-jWVnRE/eglibc-2.13/build-tree/hurd-i386-libc/mach/mach_msg_trap.S:2
+
+1  0x0105b769 in __mach_msg (msg=0x1024af8, option=258, send_size=0, rcv_size=40, rcv_name=140,
+   timeout=1000020, notify=0) at msg.c:110
+
+2  0x01062251 in _hurd_select (nfds=2, pollfds=0x1024dc0, readfds=0x0, writefds=0x0, exceptfds=0x0,
+   timeout=0x1024bbc, sigmask=0x0) at hurdselect.c:324
+
+3  0x0114427b in __poll (fds=0x1024dc0, nfds=2, timeout=1000020) at ../sysdeps/mach/hurd/poll.c:48
+
+4  0x0804b770 in iopause (x=0x1024dc0, len=2, deadline=0x1024dd8, stamp=0x1024de8) at iopause.c:29
+
+5  0x08048efc in main (argc=2, argv=0x1024e94) at runsv.c:543
+
+
+and main() shows up as:
+
+   sig_unblock(sig_term);
+
+   sig_unblock(sig_child);
+
+ ->  iopause(x, 2 +haslog, &deadline, &now);
+
+   sig_block(sig_term);
+
+   sig_block(sig_child);
+
+
+So it simply looks like the known "signals don't interrupt select" bug.
